Aim to study the variant lumbricals of hand. 100 upper limbs of 50 donated embalmed cadavers (45 males & 5 females) of age group ranging from 70 to 80 years were dissected in the department of Anatomy at K. J. Somaiya Medical College, Sion, Mumbai, INDIA. The variant lumbricals were observed in 3 specimens. The neurovascular pattern in the palm was also observed. The photographs of the variation of the lumbricals were taken for proper documentation. We observed an accessory belly of second lumbrical originating from the radial side of the flexor digitorum superficialis in one specimen, an accessory belly of first lumbrical originating from the radial side of the most radial tendon of the flexor digitorum profundus (corresponding to the index finger) in the second specimen and the high origin of the first and second lumbrical from the flexor digitorum profundus. In all the specimens lumbricals got inserted in to the extensor digital expansion near the metacarpophalangeal joint. The existence of two bellies of first lumbrical should be kept in mind by surgeons operating on hand.
